[0002] In the field of machine tool manufacturing, the stability of the bed and bed base is crucial to machining accuracy. Traditional bed frames are supported by iron pads at the bed feet. At the same time, the bed rails need to be kept horizontal when the machine tool is in use. Therefore, when debugging the machine tool, the thickness of the pads needs to be replaced or adjusted to keep the machine tool rails level.

[0003] The Chinese utility model patent with announcement number CN218696515U discloses a new type of machine tool shock-absorbing mounting structure. By setting a shock-absorbing seat, it is beneficial to improve the shock-absorbing performance of the machine tool leg structure, thereby improving the shock-absorbing performance of the machine tool, making it easier for users to use, effectively improving the processing quality of the machine tool when processing workpieces, reducing the shaking feeling of the machine tool leg structure, and making it more convenient to use. A fixed seat is set to improve the stability of the machine tool leg structure when installed on the ground.

[0004] In the prior art, simple settings are generally used for machine tool legs, and the difficulties encountered during machine tool debugging are not improved. At the same time, when the machine tool is in use, the collision between the workpiece and the tool will cause the machine tool to deviate or shake, which will also affect the accuracy of the machine tool during use.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] like Figures 1 to 4 As shown, a three-point positioning bed base includes a machine tool bed 101, and a plurality of support assemblies 102 are provided on the machine tool bed 101. The support assemblies 102 are arranged at the four corners of the machine tool bed 101, and the support assemblies 102 include support columns 201, and the support columns 201 are fixedly connected to the machine tool bed 101. The end of the support column 201 away from the machine tool bed 101 is fixedly installed with a fixed seat 206, and the outer surface of the fixed seat 206 is provided with a rubber layer for anti-slip effect. The end of the support column 201 away from the fixed seat 206 is provided with a trapezoidal thread, and an extrusion spring 205 is fixedly installed on the fixed seat 206, and the other end of the extrusion spring 205 is fixedly installed with a moving ring 204, and the moving ring 204 is slidably connected to the outer wall of the support column 201, and a side bracket 209 is fixedly installed on the outside of the moving ring 204, and a dispersion column 208 is slidably installed on the side bracket 209.

[0020] like Figures 3 to 5 As shown, an insertion seat 2071 is provided at one end of the dispersion column 208, and the insertion seat 2071 is connected to the dispersion column 208 by threads. The insertion seat 2071 is in the shape of a quadrangular pyramid, and the material of the insertion seat 2071 is gray cast iron. The insertion seat 2071 is used to be inserted into the ground for fixing. A pressure dividing seat 2072 can also be provided at one end of the dispersion column 208, and the pressure dividing seat 2072 is connected to the dispersion column 208 by threads. The pressure dividing seat 2072 is in the shape of a truncated cone, and the material of the pressure dividing seat 2072 is made of hard rubber, such as high styrene rubber, natural rubber, styrene-butadiene rubber, etc. The pressure dividing seat 2072 is used to contact the ground to increase friction.

[0021] like Figure 3 and Figure 4As shown, a limit block 213 is fixedly installed on the dispersion column 208, and the limit block 213 is slidingly connected to the side bracket 209. An adjusting shaft 210 is fixedly installed on the dispersion column 208, and a telescopic rod 212 is rotatably installed on the adjusting shaft 210. A buffer pad 214 is provided on the telescopic rod 212, and the buffer pad 214 is made of nitrile rubber. A rotating shaft 215 is fixedly installed on the movable end of the telescopic rod 212 away from the adjusting shaft 210, and the rotating shaft 215 is rotatably connected to the movable ring 204. An adjusting torsion spring is fixedly installed on the rotating shaft 215, and the other end of the adjusting torsion spring is fixedly installed on the movable ring 204.

[0022] like Figure 3 and Figure 4 As shown, the support column 201 is also provided with an adjusting knob 202, and the adjusting knob 202 is engaged with the trapezoidal thread on the support column 201. The adjusting knob 202 is provided with a plurality of slots, and the slots on the adjusting knob 202 are used to allow the device to drive the adjusting knob 202 to rotate by a hook wrench. The adjusting knob 202 is rotatably installed with an extrusion ring 203, and the extrusion ring 203 is slidably connected to the limit block 213. The extrusion ring 203 contacts the buffer pad 214, and the extrusion ring 203 can squeeze the telescopic rod 212, allowing the telescopic rod 212 to rotate around the rotation axis 215.

[0023] Working principle: When using this device, the machine tool iron pad or bed leg on the machine tool bed 101 is replaced with the support assembly 102, so that the support column 201 in the support assembly 102 is fixedly connected to the machine tool bed 101. Then, when the machine tool bed 101 is moved and placed, multiple fixed seats 206 can be allowed to contact the ground first, and then the hook wrench is used to drive the adjusting knob 202 to rotate, so that the adjusting knob 202 is allowed to squeeze the telescopic rod 212 through the squeezing ring 203, and then the telescopic rod 212 will rotate around the rotating shaft 215, so that the insertion seat 2071 on the dispersion column 208 can be inserted into the ground to achieve the effect of preventing displacement. After the machine tool bed 101 is initially fixed, it is necessary to detect the horizontal state of the guide rail on the machine tool bed 101. If the guide rail of the machine tool bed 101 is not level, it can be adjusted by rotating the adjusting knob 202.

[0024] When the present device is debugged on some surfaces where the insertion seat 2071 cannot be used, the insertion seat 2071 can be rotated to disengage the insertion seat 2071 from the dispersion column 208, and then the pressure dividing seat 2072 can be used. It is only necessary to connect the pressure dividing seat 2072 to the dispersion column 208 through threads. After that, the pressure dividing seat 2072 can also bear part of the pressure for the fixed seat 206 when in use. At the same time, the pressure dividing seat 2072 can also increase the contact area between the support assembly 102 and the ground.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
